Engel Collaborates on Solution for High-volume Production of Two-component Test Swabs
2020-06-03    [Source:Plastics news europe]

PUdaily, Shanghai —— As demand for test swabs for nasal and throat swab tests continues to soar, Austrian injection moulding machine manufacturer Engel and Hack Formenbau, a mould maker based in Germany, have developed an integrated system solution with a short lead time, enabling plastics processors to launch production without delay.


    The two companies already collaborate closely on many projects, with a focus on high-precision applications for medical technology.  “And our customers benefit from this", said Christoph Lhota, vice president, Engel medical. 
"Our customers receive a complete system that is precisely tailored to their individual requirements and can get started with series production in the shortest possible time". 


    The test swabs are designed with a stable thermoplastic handle and a head made of a thermoplastic elastomer to provide a less uncomfortable experience for the patient. Hack Formenbau developed this two-component design, initially with three different head design proposals. Handle length and shape, swab head and the materials used are adapted according to the customers' specifications. 


    A single production unit, equipped with a 32-cavity mould, and a cycle time of 6 to 8 seconds, can yield an output of up to 320 test swabs per minute and 460,000 test swabs per day.
    The swab production unit consists of a hydraulic, two-component Engel victory injection moulding machine equipped with iQ weight control for high process consistency. The iQ module detects fluctuations in the raw material and ambient conditions, and automatically compensates for them shot by shot by adapting the quality-relevant process parameters.
An integrated Engel viper linear robot automatically removes and deposits the swabs. 



    Covid-19-relevant orders are currently given priority at both Hack Formenbau and the Engel plants worldwide. However, in the future, the mould and system solution will not be used exclusively for coronavirus test swabs: the companies are also jointly developing highly efficient complete systems for the production of swabs for influenza tests or gynaecological examinations, among others.
